Descrição

Sends a request to create a prepared statement with the given parameters,
without waiting for completion.

This is an asynchronous version of pg_prepare(): it returns TRUE if it was able to
dispatch the request, and FALSE if not. After a successful call, call
pg_get_result() to determine whether the server successfully created the
prepared statement. The function's parameters are handled identically to
pg_prepare(). Like pg_prepare(), it will not work
on pre-7.4 versions of PostgreSQL.

Parâmetros

connection

PostgreSQL database connection resource. When
connection is not present, the default connection
is used. The default connection is the last connection made by
pg_connect() or pg_pconnect().

stmtname

The name to give the prepared statement. Must be unique per-connection. If
"" is specified, then an unnamed statement is created, overwriting any
previously defined unnamed statement.

query

The parameterized SQL statement. Must contain only a single statement.
(multiple statements separated by semi-colons are not allowed.) If any parameters
are used, they are referred to as $1, $2, etc.

Valor Retornado

Returns TRUE on success, FALSE on failure. Use pg_get_result()
to determine the query result.

// Execute the prepared query. Note that it is not necessary to escape // the string "Joe's Widgets" in any wayif (!pg_connection_busy($dbconn)) {pg_send_execute($dbconn, "my_query", array("Joe's Widgets"));$res2 = pg_get_result($dbconn); }

// Execute the same prepared query, this time with a different parameterif (!pg_connection_busy($dbconn)) {pg_send_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));$res3 = pg_get_result($dbconn); }
